ECOSUD is a challenge for the creation of a new science in line with Prigogine's statement that at all levels we observe events associated with the emergence of novelties and narrative elements, which we may associate with the creative power of natureA". This is not only a platform to present novel research related to ecological problems from all over the world; it also gives opportunities for new emergent ideas in science arising from the cross fertilization of different disciplines, including mathematical models and eco-informatics, evolutionary thermodynamics and biodiversity, structures in ecosystems modelling and landscapes to mention but a few. The Seventh International Conference in the well-established series on Ecosystems and Sustainable Development contains papers on the following topics: Greenhouse issues; Ecosystems modelling; Mathematical and system modelling; Natural resources management; Environmental indicators; Sustainability development studies; Recovery of damaged areas; Energy and the environment; Socio economic factors; Soil contamination; Waste management; Water resources; Environmental management.
